Marsh Ecology Research Program (MERP): Substrate core data (1980-1982)

The Marsh Ecology Research Program (MERP) was a long-term interdisciplinary study on the ecology of prairie wetlands. A scientific team from a variety of disciplines (hydrology, plant ecology, invertebrate ecology, vertebrate ecology, nutrient dynamics, marsh management) was assembled to design and oversee a long-term experiment on the effects of water-level manipulation on northern prairie wetlands. Ten years of fieldwork (1980 -1989), combining a routine long-term monitoring program and a series of short-term studies, generated a wealth of new and diverse information on the ecology and function of prairie wetlands (Murkin, Batt, Caldwell, Kadlec and van der Valk, 2000). This data set includes substrate core data, collected as part of the invertebrate setion of MERP. Invertebrate monitoring during the Marsh Ecology Research Project (MERP) has explored the effects of short- and long-term water level and associated vegetation changes on invertebrate populations. This project has produced an extensive and multi-faceted data set depicting the distribution and variation of invertebrates within a prairie wetland in flux. At each sample site during the baseline and deep flooding phases of the MERP, core samples were collected in order to obtain estimates of benthic invertebrates found in the experimental cells.
